only 15% of tweets that ordinary users get are directly from the professional media, whereas they’re the most active content-producers
– it’s not a fail but a normal rate: a generalist media talk about a wide diversity of topics, and not 100% topics interest a wide diversity of people. Hubs of conversation can happen in a second life, through search engines
– if 100% of contents that are produced were RT by billions of people, there’ll be a kind of psychiatric traffic jam. It’s a good news that people keep on filtering

20K users (or 0.05% of all Twitter users) attract 50% of the attention. Among them: bloggers, celebrities. A new influential loop: you can interact on diverse interests with diverse hubs, it’s no longer fully segmenter. Sharing and opinions can arise, where you don’t really expect them

Conversations are unequal, asymetrical and scandalously one way: you only follow back 20% of people who follow you

To conclude, it’s pretty funny that twitter success is more on what you listen (so the quality of contents producers) than what you discuss. If I’m so demanding on good media, it’s also a way to create information dependency. Who said that verticality was dead? A star-blogger, maybe.
